So I've picked up using my printer after it having been idle for a good while.

I've dusted it off and checked up on it, and done a few prints again, however looking at my octoprint log I noticed there had been some temperature drops around 30c drop, though it seems very short and it does recover, anyone have any idea's of where I should be looking to see if there is trouble with the printer.

First, try to verify that those are actual temp drops and not Octoprint errors. Try to determine if the drops correspond to any print activity. The cooling fan being directed onto the heater block rather than below the nozzle can cause this. Check fan duct alignment. Consider a silicone sock to insulate the block.
